The VP 581A SBS
Registration block has the same foot print as a micro-plate (127.7 mm by
85.5 mm and stands 18 mm tall) and is made from polypropylene.
Pre-drilled and taped (8-32) holes in the block provide a simple way to
mount/register many accessories to a robot platform deck tile location.
The VP 581B is
identical to the VP 581A except it is 12.5 mm tall
The VP 581B-PTFE
identical to the VP 581B except it is constructed from PTFE. |

The VP 581A
registration blocks have many applications. The
plate registration features on the deck tiles of some robotic platforms
interfere with the inlet or outlet nipples on the
VP 549ETOH
or VP 549H2O spillway reservoirs. We have solved this problem
by placing 4 alignment holes in the bottom of the reservoirs (arrows).
The photo to the right illustrates the bottom view of the reservoir and the
top view of a VP 581A SBS locating block. The alignment holes register
to 4 set screws in our VP 581A. Thus we are able to stack the
reservoir on top of the SBS locating block and elevate the reservoir above
any obstruction.

All of our Bubble Paddle Reservoirs can
be mounted on a polypropylene block with SBS microplate
dimensions (VP 581B). Mounting is done by drilling and
tapping holes in the bottom of the reservoir. When
ordering your reservoir also order VP 581B
with modification and your
reservoir will be attached to a VP 581B SBS feature.
This will allow your Bubble Paddle Reservoir to be placed in
the portrait position of the following Tumble Stirrers
VP
710C-1, VP 710C1-7, VP 710G6, VP 710MXL7T, VP 710MXM7T
The advantages of the SBS
feature on the bottom of the reservoir is two fold:
1. It will the
position the reservoir so a robotic pipettor will be able to place the
pipet tips in the correct locations between the bubble paddles.
2.
The reservoir can be taken off the deck and replaced in exactly the same
position.

Designed to meet the
high temperature requirements of scientists to heat plates on a robot deck.
The "cut away" low profile design allows the
robot plate handler to move the plates around the deck between multiple
heating stations and cooling stations. To accommodate the 200C heat
of the VP 741BW we recommend the VP 581B-MICA
because Very High Temperature Mica "Muscovite Mica"
is able to accommodate higher temperatures than
Polypropylene or PTFE.

VP 381O is simple
registration device that allows the researcher to reformat plates from 96 to
384 or the reverse using a 96 Pin Tool. The reformattor has a VP
581B SBS
footprint on the bottom that fits into a deck station on a robot deck.
When a 384 well microplate is placed on 1 of the 4 positions of the Reformattor, the 96 pin tool
or pipetor will be aligned to the same relative quadrant
of the microplate. The entire 384 well microplate is addressed when
the 384 well microplate is manually moved between the 4 positions

One of the problems
working with PCR Plates is that often they are warped. This is
especially true after they have been through many heating cycles in a
thermocycler. Warped
plates present several practical problems for pipetting or pin tool
applications as corner wells are higher than center wells and well center to center
spacing is also affected. Warped PCR plates can also cause disastrous
crashes of automated liquid handling robots.
A customer sent us
some PCR plates that were warped and asked if we could solve the
problem. The VP 581 Plate Flattener and the VP 581A Adapter Block are
simple but effective solutions. |

The VP 581 is
designed with a groove in 3 sides that capture the lip of a PCR plate.
Simply slide the plate in the groove from the open (4th) side and the plate is
flattened. The VP 581 Plate Flattener can be attached to the robot deck
via 3 screw holes that are drilled on 50.8 mm centers. This is the
same spacing as on the PerkinElmer Multi Probe deck shown in the photo.
An alternative to screwing the Plate
Flattener into the deck is to attach it to the VP 581A Adaptor Block using
the same 3 screw holes. Its dimensions are 127.7 mm long by
85.54 mm wide and 18. mm tall. The photo to the right illustrates how
the VP 581 is attached to a VP 581A Adaptor Block and then fits onto a Multi Probe
microplate holder. By using this simple Adaptor Block you can locate
the flattened PCR plate any where on the robot deck that has a plate holder.
This system is also compatible with many robot plate handlers.
The VP 581 was designed to flatten the
Robbins Scientific CyclePlate®
-384DW Thin Wall PCR
plates which have a 3.16 mm thick lip. PCR plates with thicker or
thinner lips can also be accommodated with some simple modifications.
Send us a sample plate and we will provide a custom solution for you.
Another application for the VP 581 is to
provide a very precise registration for 1536 well microplates. With
these plates there is no place for "wiggle room". |

The VP 581A adapter can also be used to
mount and locate Bubble Paddle Stirrers to workstation plate holders.

The VP 581R-PE was designed so the
bottom has same dimensions as a microplate (SBS)and top
flares out for a pocket that can accommodate a microplate. We made it to accommodate some of our wash
stations that had tubing connectors that interfered with the robot
deck plate holders. This design places the tubing connectors above
the obstructions on the plate holders.

The
VP 581A-MICA was designed to attach to the bottom of our
heat blocks and locate the heat block in a microplate holder
on a robotic deck. The heat blocks are attached to the
VP 581B-MICA so that the microplates they hold, will be in
the same relative position as if they placed in the holder
on a robotic deck. Thus the robot will not have to be
reprogrammed to find the correct X and Y positions.

The VP 581A-MICA
is
made from Muscovite, a very high temperature stable Mica
which is dimensionally stable over a temperature range of
-80C to 500C. This is a very important characteristic
as high temperatures can induce swelling of polypropylene
and PTFE material to the point where they won't fit in the microplate holders on the robot deck. This
heat induced swelling of
material is a problem for our polypropylene and PTFE
versions of the VP 581A and the reason we developed the VP
581A-MICA. We recommend this product over the other
materials we have used for heat blocks in the past.
The Muscovite Mica is also a good
insulator and a way to prevent or reduce heat from the heat
block transferring to the robot deck. The
Muscovite Mica is safety rated by UL laboratories as UL
94VO.

The
VP 581B-MICA is almost identical to the VP 581A-MICA
except in the thickness. The
VP 581B-MICA is 6 mm shorter than the VP 581A-MICA.
This facilitates applications where the Z height is limited.
Also the shorter height translates to a lower price.
The VP 581B-MICA was designed to attach to the bottom of our
heat blocks and locate the heat block in a microplate holder
on a robotic deck. The heat blocks are attached to the
VP 581B-MICA so that the microplates they hold, will be in
the same relative position as if they placed in the holder
on a robotic deck. Thus the robot will not have to be
reprogrammed to find the correct X and Y positions. |

The VP 581C-AL was designed to keep the
contents of a microplate cool while on a robotic work
station. Made from block of solid aluminum 2.54 cm
thick the
VP 581C-AL will keep a microplate between 7C and
10C for over 15 minutes.
Follow this link to data showing the
ability of the VP 581C-AL to stabilize the temperature of a
96 well microplate with 300 ul of distilled water in each
well. The VP 581C-AL were either chilled to 7.8C or
-13C prior to placing on the robot deck. |

The VP 581-VPREP was designed to provide a more
precise deck microplate holder for the Velocity 11 VPREP now
Agilent Vertical work station. The original VPREP
microplate holder provided a loose fit with some pipet tip
boxes so we made an accessory that would fit snugly in the
VPREP deck holder and would accommodate the tip boxes
precisely.

VP 581-PE is included with the
VP 710C1-M
which allows a Tumble Stirrer to
be precisely positioned on
the deck of many different robot platforms (including the Tecan Evo, Caliper Sciclone, Hamiliton Microlab, Star and
many others). |

The VP 581-PE-2 was designed to attach to the deck of a PerkinElmer EP3 or Janus
robot using the two locating pins on the bottom of the VP 581-PE-2 and the
locating holes in the both the EP3 and Janus decks. A variety of accessories
can then be attached to the VP 581-PE-2.

with a
VP 756CM-P0 is attached. |

Patrick:
I saw the Robbin's 384 well plate holder on the VP site. I hope you sell a lot
of them! They have worked fantastic for us! They hold a lot of plates not just
the Robbins. And even non-warped plates are positioned much more precisely than
they would be otherwise. I imagine they would be useful for 1536 and higher
plates for which the positioning tolerances are very low!!
